- C.
  
  Conical flasks (also called Erlenmeyer flasks)
Correct Answer
C. Conical flasks (also called Erlenmeyer flasks)

Explanation
The correct answer is "Conical flasks (also called Erlenmeyer flasks)". Conical flasks are commonly used in laboratories for mixing, heating, and storing liquids. They have a conical shape with a narrow neck and a flat bottom, which allows for easy swirling and mixing of liquids. Erlenmeyer flasks are another name for conical flasks, named after the German chemist Emil Erlenmeyer who popularized their use. These flasks are often used in chemistry experiments and are known for their versatility and ease of use.

  This Bunsen burner has the safety flame
- B.
  
  This Bunsen burner has the heating flame
- C.
  
  This Bunsen burner has the cooking flame
Correct Answer
B. This Bunsen burner has the heating flame

Explanation
The correct answer is "This Bunsen burner has the heating flame" because a Bunsen burner typically has two types of flames - a safety flame and a heating flame. The safety flame is a small, non-luminous blue flame used when the burner is not in use or when a low heat is required. The heating flame, on the other hand, is a larger, luminous blue flame used for heating purposes. Therefore, if the Bunsen burner is being used for heating, it would have the heating flame.
